This Dominic I video provides a visual overview of 36 atmospheric nuclear devices detonated in the Pacific Proving Ground from April to November 1962. It was the last atmospheric nuclear test series conducted by the United States. Also, Dominic I was the largest and most elaborate U.S. testing operation ever conducted. In geographic terms, the diagnostic stations receiving data from the tests covering more than 15 million square miles. According to the video, Operation Dominic I was prompted by...

DOMINIC I was an atmospheric nuclear weapons test series conducted in the Pacific Ocean area in 1962. It included 5 high-altitude shots at Johnston Island, 29 airdrop airburst events near Johnston and Christmas Islands, one Polaris-launched airburst in the Christmas Island area, and one underwater test in the Pacific Ocean off the United States West Coast. This is a report on DOD personnel with an emphasis on operations and radiological safety.

One of the most sensitive measures of a change in electron content in the lowest portions of the ionosphere is the received phase of a VLF signal. Such measurements have been used for years to monitor sudden ionospheric disturbances (SID) in the lower ionosphere. Phase differences equivalent to a change of a few electrons per cubic cm or an effective ionospheric height change of less than 1 km can be detected.

Operation HARDTACK I consisted of 35 nuclear tests conducted at the Pacific Proving Ground between April 28 and August 18, 1958. These tests included balloon, surface, barge, underwater, and rocket-borne high-altitude tests. The first test, Yucca, was a nuclear device attached to a helium balloon launched from the USS Boxer near Enewetak Atoll. HARDTACK I consisted of three portions; the first was the development of nuclear weapons. This was a continuation of the type of testing conducted at...

Operation ARGUS was a series of three high-altitude nuclear tests conducted by the Atomic Energy Commission in the South Atlantic Ocean in August and September 1958. The results of Operation ARGUS proved the validity of the Christofilos Theory. This theory proposed that a radiation belt is created in the upper regions of the Earth's atmosphere by high-altitude detonations. The radiation belt affects radio and radar transmissions, damages or destroys the arming and fuzing mechanisms of...

The President has directed the Atomic Energy Commission (AEC) and the Department of Defense (DOD) to plan for a series of nuclear tests starting approximately 1 April 1962. These tests will be conducted in the Pacific Ocean in the general area of Christmas and Johnston Islands. The unclassified nickname for this operation is Dominic. SAC's participation in these tests is as outlined in this operations order.

The question, under what geometric assumptions on a space X an n-quasiflat in X implies the existence of an n-flat therein, has been investigated for a long time. It was settled in the affirmative for Busemann spaces by Kleiner, and for manifolds of non-positive curvature it dates back to Anderson and Schroeder. We generalize the theorem of Kleiner to spaces with bicombings. This structure is a weak notion of non-positive curvature, not requiring the space to be uniquely geodesic. Beside a...

It is believed that superselection rules in quantum mechanics can restrict the possible operation on a qbit. If this was true, the model used by Mayers for the impossibility of bit commitment and by Kitaev for the impossibility of coin flipping would be inadequate. We explain why this is not the case. We show that a charge superselection rule implies no restriction on the operations that can be executed on any individual qbit.

If X is a smooth manifold then the R-algebra C^\infty(X) of smooth functions c : X --> R is a "C-infinity ring". That is, for each smooth function f : R^n --> R there is an n-fold operation \Phi_f : C^\infty(X)^n --> C^\infty(X) acting by \Phi_f: (c_1,...,c_n) |--> f(c_1,...,c_n), and these operations \Phi_f satisfy many natural identities. Thus, C^\infty(X) actually has a far richer structure than the obvious R-algebra structure. We develop a version of algebraic geometry...

Bipartite operations underpin both classical communication and entanglement generation. Using a superposition of classical messages, we show that the capacity of a two-qubit operation for error-free entanglement-assisted bidirectional classical communication can not exceed twice the entanglement capability. In addition we show that any bipartite two-qubit operation can increase the communication that may be performed using an ensemble by twice the entanglement capability.

We present general methods for simulating black-box Hamiltonians using quantum walks. These techniques have two main applications: simulating sparse Hamiltonians and implementing black-box unitary operations. In particular, we give the best known simulation of sparse Hamiltonians with constant precision. Our method has complexity linear in both the sparseness D (the maximum number of nonzero elements in a column) and the evolution time t, whereas previous methods had complexity scaling as D^4...

We investigate a class of nominal algebraic Henkin-style models for the simply typed lambda-calculus in which variables map to names in the denotation and lambda-abstraction maps to a (non-functional) name-abstraction operation. The resulting denotations are smaller and better-behaved, in ways we make precise, than functional valuation-based models. Using these new models, we then develop a generalisation of \lambda-term syntax enriching them with existential meta-variables, thus yielding a...

The operation of zig-zag products of graphs is the analogue of the semidirect product of groups. Using this observation, we present a categorical description of zig-zag products in order to generalize the construction for the category of simple graphs. Also, we examine the covering properties of zig-zag products and we utilize these results to estimate their spectral invariants in general. In addition, we provide specific spectral analysis for some such products.

Adiabatic quantum transistors allow quantum logic gates to be performed by applying a large field to a quantum many-body system prepared in its ground state, without the need for local control. The basic operation of such a device can be viewed as driving a spin chain from a symmetry protected phase to a trivial phase, and this perspective offers an avenue to generalise the adiabatic quantum transistor and to design several improvements. The performance of quantum logic gates is shown to depend...

Two-qubit operations may be characterized by their capacities for communication, both with and without free entanglement, and their capacity for creating entanglement. We establish a set of inequalities that give an ordering to the capacities of two-qubit unitary operations. Specifically, we show that the capacities for entanglement creation and bidirectional communication without entanglement assistance are at least as great as half the bidirectional communication capacity with entanglement...

Nanopores made with low dimensional semiconducting materials, such as carbon nanotubes and graphene slit pores, are used in supercapacitors. In theories and simulations of their operation, it is often assumed that such pores screen ion-ion interactions like metallic pores, i.e. that screening leads to an exponential decay of the interaction potential with ion separation. By introducing a quantum capacitance that accounts for the density of states in the material, we show that ion-ion...

The two-dimensional cluster state, a universal resource for measurement-based quantum computation, is also the gapped ground state of a short-ranged Hamiltonian. Here, we examine the effect of perturbations to this Hamiltonian. We prove that, provided the perturbation is sufficiently small and respects a certain symmetry, the perturbed ground state remains a universal resource. We do this by characterising the operation of an adaptive measurement protocol throughout a suitable...

Ground states of spin lattices can serve as a resource for measurement-based quantum computation. Ideally, the ability to perform quantum gates via measurements on such states would be insensitive to small variations in the Hamiltonian. Here, we describe a class of symmetry-protected topological orders in one-dimensional systems, any one of which ensures the perfect operation of the identity gate. As a result, measurement-based quantum gates can be a robust property of an entire phase in a...
